# $NetBSD: extract.mk,v 1.3 2006/06/06 16:33:48 rillig Exp $
#
# The following variables may be set by the package Makefile and
# specify how extraction happens:
#
# EXTRACT_CMD is a shell command list that extracts the contents of
# an archive named by the variable ${DOWNLOADED_DISTFILE} to the
# current working directory. The default is ${EXTRACT_CMD_DEFAULT}.
#
# EXTRACT_OPTS is a list of options to pass to the "extract" script
# when using EXTRACT_CMD_DEFAULT. See the comments at the head of
# the "extract" script for a definitive list of the available
# options. The default list is empty.
#
# EXTRACT_USING specifies the tool used to extract tar/ustar-format
# archives when using EXTRACT_CMD_DEFAULT. The possible values are
# "gtar", "nbtar", and "pax". By default, we use the "nbtar" tool
# (pkgsrc's pax-as-tar).
#
# EXTRACT_ELEMENTS is a list of files within the distfile to extract
# when using EXTRACT_CMD_DEFAULT. By default, this is empty, which
# causes all files within the archive to be extracted.
#
# The following are read-only variables that may be used within a package
# Makefile:
#
# DOWNLOADED_DISTFILE represents the path to the distfile that is
# currently being extracted, and may be used in custom EXTRACT_CMD
# overrides, e.g.
#
# EXTRACT_CMD= ${TAIL} +25 ${DOWNLOADED_DISTFILE} > foo.pl
#
# EXTRACT_CMD_DEFAULT uses the "extract" script to unpack archives. The
# precise manner in which extraction occurs may be tweaked by setting
# EXTRACT_OPTS, EXTRACT_USING and EXTRACT_ELEMENTS.
